<dd><p>This directive instructs assembler to add an undefined reference to
the symbol following the directive.  The maximum symbol name length is
1023 characters.  No relocation is created for this symbol; it will
exist purely for pulling in object files from archives.  Note that
this reloc is not sufficient to prevent garbage collection; use a
KEEP() directive in the linker file to preserve such objects.
